Nanay Gloria's serves authentic Filipino dishes buffet-style. What you should expect from here is an abundance of food that sticks close to traditional Filipino culture. The food reminds me of the things made by your titas or lolas. I'm the type of person who really likes eating at places like this because it reminds me of the Filipino home cooking from my family that I truly miss.
They have two rooms: a room with the buffet line and tables with chairs and the other room with booths and a water dispenser. They did not have a soda fountain, so all the drinks have to be purchased from their mini-market section next to the register.
All the staple dishes are there: kaldereta, kare-kare, sisig, fried bangus, etc. I don't think they have a set menu, either. So you might not see some of the things I listed, but I'm pretty sure the popularly requested ones are always put out. Try their chicken tinola or the chicken adobo if you just want a common cultural dish. I was skeptical about their sisig at first, but when you try it I'm pretty sure it'll wow your tastebuds like it did mine.
If you have an appreciation for true Filipino cooking, then this is the place for you. Don't expect anything but the full cultural flavor from the Philippines.
