Went there late on a Sunday night and there were still people in line. The hot dog was overcooked so there wasn't a snap to it rather a dull char on the ends. Also, be picky about your condiments. Don't get "everything" on it or else it'll be too busy.
The fries are great. You definitely get a lot. Also, if you just order a hot dog and fries, they'll be nice enough to tell you to get a drink and save a few cents on the combo. The place isn't that great, but it does serve as comfort food for the Oakland area.
