There’s a bar here with that aesthetic. They do serve ok burgers at slightly reasonable prices, but the secret is to become friends with the cooks. Then tell them that you don’t care what the upcharge is, but you want them to make you the burger they’d want and to have fun with it.
Now I can go in and say “Tell them TexasDrunk wants whatever burger they want to send out” and 9 out of 10 times I get a burger that’s delicious (and sometimes insane). Usually they just charge me the regular burger price.
I don’t do it often, but I got good friends and good burgers out of it.
