Quick eats around Royale
I'm going to a concert at the Royale (279 Tremont). Might be in a rush. Can you suggest a place for a quick bite before the show? Chinatown is nearby, but I don't think I'll have time for a sit-down meal so something like Peach Farm is out. I'll be coming on the Red Line / Park Street. Thanks. (Edit: It'll be around 8:30-9PM.)
Definitely 2nd McSlim's Pho Hoa recommendation. The owners are friendly, the pho is good (and cheap) and they can easily get you out in 30-40mins tops. Decide what you want to eat ahead of time and you can probably get out even quicker. If pho isn't your thing they do a good grilled pork/rice plate with fish sauce.
This is my go to before a show in the theater district area mainly because it's cheap and the food doesn't make me feel bad.
A few decent, nearby quick-service or brisk sit-down dining options:
Four Burgers -- a quality $8 fast-food burger, good salmon-, turkey-, and veggie-burger alternatives, too
Bento Express -- respectable fast-food Asian, including ramen & udon soups, bento-boxes, rice plates, and sushi
Maria's Taqueria -- decent if not mind-blowing tacos and burritos
Pho Pasteur or Pho Hoa -- sit-down, but pretty easy to get in and out if you order quickly, and they do quality pho
Irashai -- modest sushi and teryaki joint
Jacob Wirth -- good for a quick burger and beer at the bar, doable if it's slow (avoid the German food).
