Eh, it's Denny's. Point to the menu, pantomime a baseball swing, and say "Grand Slam."

I just pointed and asked them in the very broken Spanish I do know

Denny's menus are loaded with photos so it's easy enough for them to order.

Haha reminds me of how I was hosting at my restaurant and this table of 18 French people came in and since I'm the only one that speaks French out of 50 employees they panicked and made me switch jobs and serve the table instead while my manager covered hosting

Did any of the bottoms speak English?

OP, what's a "25 top table?"

It means 25 person table. Top is like head.
