decent but not expensive places near Nob Hill Masonic Center?

[ceviche]

hi everyone,
we're going to be seeing a show at nob hill masonic center on friday night at 7:30pm and were hoping to have dinner beforehand within walking distance of the venue. everything i've seen either seems low-end or expensive. not much in the middle ($15-20 per entree or so). any tips? open to any cuisines. thanks!
