Aina is a weekend brunch pop up in the former 903 space. The food is new Hawaiian, so add it to the short list of Asian-inspired brunch spots: http://chowhound.chow.com/topics/885135
The food was prepared with care, and gorgeously plated. The smoky short ribs (kalbi loco moco) had a delicious bit of fat on the edge, and were a good breakfast alternative to Wise Sons' pastrami. The eggs were lightly cooked, and their yolks freely ran to flavor the other components of the dish. The rice that came with the short ribs was a perfectly cooked vehicle for the eggs too–– it held together, was not too compact, and was not too sticky.
In another dish, smoked mushrooms complemented Chinese sausage (lap cheung). The sausage was thinly sliced, crisped up, and it puckered up into little cups that held the eggs and kabocha squash puree. Once they get settled, I hope they'll switch to a better brand of lap cheung like from Chinatown's Mow Lee Shing Kee & Company.
The two main dishes were more than plenty for two people, but because I wanted to feel like crap the rest of the day, we also got a half order of the taro and guava french toast. It went well with the coconut foam.
We got there en route to the Saturday Alemany Farmer's Market, and got counter seating without a problem at about 9:30am. They don't take reservations and quickly filled up as we ate our meal. There is also public seating/tables outside if you're willing to grab food from inside and bus yourself.
Make sure to check their website to see if they're open-- they close the last weekend of each month, and have some vacation time planned in the next few weeks. Hours are 9-2, but the website notes they might close early depending on demand.
