I'm looking for a place walking distance from the Orpheum where my friends and I can go and have drinks and appetizers before going to the show. Any suggestions?

On the side there is a place they sell food

Umami burger is solid. There are plenty of places on the same street as the Orpheum to get appetizers and Drinks or Even Dinner. The Theater has a bar downstairs also.

Terroni is about a 2 minute walk from the theater, good food and nice bar. There is paid parking directly across the street from the restaurant you can keep your car there until the show ends.
