I don't know about you, but when I go to new restaurants and bars, I have a couple of standby orders I use to assess whether I'm going to want to come back.
Sandwich - Reuben
For me, a good Reuben is a few slices of corned beef, about the same amount of sauerkraut as beef, a slice of Swiss cheese and Russian dressing on toasted - but not greasy - rye bread. I can live with some of the variations, like marbled rye or pastrami, but those are small strikes against a place. Too much meat and not enough kraut are the most common felonies.
Drink - Martini
Pretty simple. Gin and olives. If you can't figure out how to put chilly gin in a glass with some big, tasty olives, I'm pretty sure you can't be trusted to make a sidecar. I know, I know, vermouth. I'm with Churchill on this one.
Pizza - Italian sausage, bell peppers, onions, thin crust.
I eat other pizzas, but this combo will uncover any fault, whether it's subpar toppings, flimsy crust, incompetent baking or insipid sauce.
The funny thing is that even though that's what I order to find out if a place is good, I'd really rather have a peanut butter and raspberry jam sandwich on toasted wheat bread and a glass of bourbon. I'll stick with that pizza, though.
