I'm at this Trader Joe's quite often. I love being able to walk in and get a couple of really good dinners for the next couple nights, and not feel like I have to buy $100 worth of stuff in the process. Their wine selection is great and reasonably priced, and they offer some hard to find cheeses and other things you won't find at your average grocery store.
Their frozen section is the jam. There are great options for quick meals and cool frozen desserts which can be great for entertaining (or just pigging out).
It can be really busy at times, and when it is, it will take you a while to navigate the store and check out. While a lot of things are a good value, some things at TJs are overpriced. There are certain things that you are better off getting at a traditional grocery store, which can be frustrating if one stop shopping is your goal. Occasionally, the cashiers will try talk your ear off, but it's alright because they're being friendly. It's much better than the blank stare you get at some stores...You know the one, the "I'm judging all your purchases while scanning them over the beepy thing and just hoping deep down inside that you don't question a price or tell me that something was on sale"...That look.
For all those reasons (and likely numerous others), Trader Joe's is great. Definitely recommend.
