drawing circles and squares with TikZ

Question

I am trying to recreate the following sketch using tikz. I found this example to draw circle but combining it with a grid to generate the following picture is a bit difficult.

How can I generate the above figure in latex?

\documentclass[tikz, border=2pt]{standalone}
\usetikzlibrary{calc}
\usetikzlibrary{math}
\usetikzlibrary{arrows.meta}
\begin{document}
\begin{tikzpicture}[line width=3pt]
  \tikzmath{
    \r = 3;
    \R = (pi * \r + \r)/2;
    \l = sqrt(pi)/1.5 * \r;
  }
  \coordinate (O1) at (0, 0);
  \coordinate (O2) at ($(O1)+(1.5*pi*\r, 0)$);
  \coordinate (O3) at ($(O1)+(3*pi*\r, 0)$);
  \filldraw[fill=lightgray, draw=black] (O1) circle [radius=\r];
  \draw (O2) circle [radius=\r];
  \draw (O3) circle [radius=\r];
  \draw[fill=red, draw=black] (O2) ++(-.65*\r, -7/6*\r) rectangle ++(\l, -\l);
  \draw[fill=red, draw=black] (O3) ++(-2.3*\r, -0.5\r) rectangle ++(\l, -\l);
\end{tikzpicture}

\end{document}

Using the example, I change the code but there is red line passing centers of circle that I can not remove and I do not know how to add text to the \draw command for labels.

Update: Just for illustration and showing current problem of combining @marmot and @Zarko, after compiling the following answer:

                      inner sep=1pt, outer sep=0pt, label distance=3pt},

\node[dish, label={[red]270:A},
            label={[blue]225:C},
            label={[green]135:B}] {Dish\\ 1};
\node[dish, label={[red]45:A},
            label={[green]270:B}] {Dish\\ 2};
\node[dish, label={[blue]280:C}]{Dish\\ 3};
\end{tikzpicture}
\end{document}

the compiled picture looks like this:

Why did two columns of matrix got separated?

You will get more help here if you show us what you have done so far. The "scope" environment is helpful if you want to combine two separate elements; you can use it to move one of them over a bit. — Thruston, Jun 10 '18 at 12:27

That's a proposal for the "filled grid".

\documentclass[tikz, border=2pt]{standalone}
\usetikzlibrary{calc,positioning}
\usetikzlibrary{math}
\usetikzlibrary{arrows.meta}
\begin{document}
\begin{tikzpicture}[line width=3pt,font=\sffamily]
  \tikzmath{
    \r = 3;
    \R = (pi * \r + \r)/2;
    \l = sqrt(pi)/1.5 * \r;
  }
\tikzset{gnode/.style={fill=gray!50,draw=gray!50,line width=1pt},
bnode/.style={fill=black,draw=black,line width=1pt}}  
\matrix [column sep=1pt,nodes={minimum size=5mm,rounded corners=2pt}] (mat) {
\node [gnode] {}; & \node [gnode] {1};
& \node [gnode] {2}; & \node [gnode] {3};\\
\node [gnode] {A}; & \node [bnode] {}; 
& \node [bnode] {}; & \node [draw=purple,fill=gray!50,line width=1pt] {}; \\
\node [gnode] {B}; & \node [bnode] {}; 
& \node [bnode] {}; & \node [bnode] {}; \\
\node [gnode] {A}; & \node [bnode] {}; 
& \node [draw=red,fill=gray!50,line width=1pt] {}; & \node [draw=red,fill=gray!50,line width=1pt] {}; \\
  };
\node[above=0pt of mat]  {Customers};
\path (mat.south west) -- (mat.north west)
node[midway,sloped,above]  {Dishes};
\end{tikzpicture}

\end{document}

thanks for the answer but first of all how can I put them together in two columns because my attempt to do it fails.. – Dalek Jun 10 '18 at 14:41
@Dalek If you want to combine that with Zarko's answer, just change its position, e.g. \matrix [column sep=1pt,nodes={minimum size=5mm,rounded corners=2pt}] (mat) at (8,0) ... (added at (8,0)). – Jun 10 '18 at 14:48
sorry, I can not reproduce above figure in my tex document. – Dalek Jun 10 '18 at 15:03
@Dalek sorry to hear that but my MWE works. – Jun 10 '18 at 15:14
I do not know why even when I compile your script in mine I get this pic? – Dalek Jun 10 '18 at 15:17

@Dalek I need to go now, will be back later but if my MWE (compiled as a whole) gives you that, then there is something fundamentally wrong with your TeX installation. – Jun 10 '18 at 15:19
I am running my latex file in sharelatex though. – Dalek Jun 10 '18 at 15:25

Thanks for the answer. I am also wondering how to make a filled grid combined with text on its first row and column (The right hand side of the above picture) ? — Dalek, Jun 10 '18 at 13:41
@Dalek, later, in the evening (CET). now you have starting point for own effort -:) — Zarko, Jun 10 '18 at 14:32
well, now is early evening, and i find spare time to finish my answer. however, you can combine mine and @marmot answer :-) — Zarko, Jun 10 '18 at 16:31

Just for sport and practice the positioning options, even for matrices, and thanks to the 2 great answers, the code that I made adding some text manipulations and structured coding practices so that it is not so obscure for beginners like me.
