I really like this spot! It's cute and cozy and seriously who doesn't need a grillcheese every once in a while. Wifi is fairly reliable-it's just the city network. Clean and bright. Pretty good staff. Very bilingual. There is a surprising amount of space considering how small the square footage is. Having said that though, I'm sure you could easily run into a situation in which you have no place to sit. Just take it to go and head to the park.
I'm giving four stars instead if five for totally picky things like a restroom crowded with boxes and cleaning supplies, and the fact that they really need to hang some art up in the back. Or mirrors. That space is so claustrophobic...
Also, they should serve toast. There is a whole ARTISANAL TOAST revolution, I think these guys could pretty easily serve the butter and jam variety. I mean, toast is literally grillcheese minus the cheese.
Bur other than those picky things, it's great! Would recommend grabbing a couple of sandwiches to take for a picnic once the weather shapes up.
