I was thinking Taqueria la Benedicion (food truck) in Jessup was Salvadorean-run for some reason, but there's a bunch of pupuserias in the area too.

It doesn't seem like there's as much Mexican food here since a lot of it is also Peruvian, Salvadorean, etc. but we've consistently had good experiences with Taqueria Los Primos. As long as they're not super packed the food is done pretty quickly too.

Roggenart has a few locations, but they can get pretty busy.

It's not really a coffee shop, but Bonheur Patisserie & Deli always has a ton of variety and they sell coffee in addition to the baked goods and sandwiches. We've pretty much always had good experiences there.

Edit: Also, Decadent is towards Laurel and has a bunch of coffee options in addition to baked goods. I think they sell Irish coffees there too.

I have a 2 bed 2 bath and we average about $35/mo here. $100 definitely seems high.
