I finally tried Spork this last week for the first time and had an amazing food experience.
The atmosphere is really nice inside - a little chic industrial, but not obnoxiously so. It kind of reminds me of a more spacious and private-seated Salt (may it rest in peace).
This sort of place is inevitably going to get negative reviews from people who have expectations that a single plate that costs $11 is going to be enough to stuff them like a foie gras goose for the meal and have leftovers to spare. If you want this - please go to Mad Mex. This isn't that kind of restaurant. This is small, intentional carefully plated gourmet plates with interesting and unique ingredients, cooked to perfection.
For both the dinner and Sunday brunch I went to, we averaged about 2 plates per person and walked out feeling full. Some plates are quite small (waffle) while others are huge (coffee steak). The waitstaff was very helpful in properly setting expectations.
Both brunch and dinner had a pretty large set of vegetarian and gluten-free menu items. I didn't ask about how careful they are about gluten separation, but it is good that at least the menu is labeled and they're thinking about it!
Cocktails were quite pleasant, though all slanted a bit on the sweet side and perhaps a bit stingy in quantity. My brunch pomplamoose cocktail seemed to disappear a bit too quickly (though i did just spend over 2 hours in Home Depot prior - probably needed it!)
It would be good to see a few more bitter/complex cocktails on the menu to balance it out. I've yet to try going off-menu to see how creative they can get, but am excited to return and see!
