I go to Trader Joe's for their frozen food and iced tea.
The Pomegranate Green Iced Tea My favorite iced tea of all time. It does run me a dollar fifty per 34oz bottle, but this is much better than my efforts at recreating it.
Although I do my other grocery shopping at Fry's primarily due to proximity to my home, I do find that the quality of the freezer food for a bachelor like myself is quite good. Variety is a plus as well.
I should also mention that there is not a grocery store who cares more about their checkout lines not being an issue than Trader Joe's. Someone is always on top of it and employees are constantly being pulled back to the checkout in short order when needed.
I don't give a whole lot of 5/5's but I can't say I've had a poor experience at Trader Joe's....ever.
