I'll take exactly one side of puns

At the Triangular Cafe:

4 different main dishes, 3 different sides and 3 different desserts

By rule of product , the number of meals is $4(3)(3)=36$

At the Mobius Strip Grill:

4 different main dishes, 1 side and 3 different desserts

By rule of product , the number of meals is $4(1)(3)=12$

Finally, the difference is

$36-12=$ $\boxed{\color{#D61F06}24~meals}$

At both the Triangular Caf $\acute{e}$ and the M $\ddot{o}$ bius Strip Grill, there are 4 main dishes and 3 desserts. In order to find the total number of possibilities, we multiply, so there are $4\cdot 3 = 12$ main dish-dessert combinations. The Triangular Caf $\acute{e}$ has 2 more sides than the M $\ddot{o}$ bius Strip Grill, so the total number of meals is $12\cdot2 = 24$ greater than that of the M $\ddot{o}$ bius Strip Grill. Alternately, we find the number of meals at each restaurant and then subtract. This yields $(4\cdot 3\cdot 3) - (4\cdot 1\cdot 3) = 36 - 12 = \boxed{24}$ more meals at the Triangular Caf $\acute{e}$ .

P.S. If any of you know how to format the $\acute{e}$ or $\ddot{o}$ without having to put it into $LaTeX$ style, could you please tell me how so it doesn't look weird with the rest of the text? Thanks!
