Burger, nachos , wings -- ZZZZZZ
Check out on - line menus for places in Boston, Montreal, Portsmouth NH, Portland ME, Portland OR, Austin , etc. I'd just do a search on TripAdvisor for best restaurants or best grill and just steal from the best.
Also, feature a local ingredient , local brews, Keep the menu small , ingredients fresh the service prompt .
Of course, execution is what keeps people in business.
