So I had a midnight craving and ventured out of downtown to Zet's. This place has been around as long as The Bay and is open 24 hours.
No frills restaurant that caters american and Greek food. You order, you pay, they prepare the food in front of you and you go get a table in the dining room. Fast service, cheap, convenient and HUGE portions.
I had the Fish and Chip's (4/5). Fish tasted good, but it had a little too much batter and the tartar sauce was not house made but served into Kraft's brackets. Otherwise would have been perfect.
They only take cash. Make sure you have some, Worst case they have ATM's on-site. Price is really reasonable for the portion you get. They have about 20 menu options and a all-day breakfast. Staff was pleasant. Even if they were busy and in a rush they were still joking with waiting customers.
