I had breakfast yesterday at the Grubstake. I think it was the first time I've been there before 2 a.m.
We stuck to American food, but the list of Portuguese specialties seems to be growing. Aside from caldo verde and bacalao, they have a rib eye with garlic, prawns, sauteed pork chops. These entrees cost considerably more than the diner food but are still only ~$15.
Breakfast is a good deal; I think we spent $18 for two with a tip. Service is low key and friendly, ideal on a lazy Saturday. I got the combo (2 eggs, pancakes or French toast, sausage or bacon). The poached eggs hit the spot. French toast was fluffy but made with unexciting white bread. Sausage was great.
He got a huge burger but put a ton of mayo on it before I could try it. It looked great. The fries are made from fresh potatoes, with skins on, and they were okay.
The food's nothing fancy, but it's comfortable and good.
If you'd be interested in a Portuguese chowdown, e-mail me. The flyer promises they can do a special meal for a minimum of six, but there are plenty of items on the everyday menu. They list about 15 Portuguese wines.
If you know anything about Portuguese food, all the better. I spent a week in Portugal once and ate a lot of baked egg custard tarts and platters of grilled sardines with cheap wine. I'd expect more home cooking than haute cuisine.
