I don't live far from this coffee shop and I drive by it a lot. Obviously the name (and the fact that you can see the inside when you drive by) always made me a bit curious so I FINALLY decided to give it a try recently & I'm a fan!
I just went with a vanilla iced coffee & it was delicious. Since I had never been here before I figured I'd let the barista talk me into something. I forget her name, but she was very nice and knowledgeable about the product at Bikini Beans. Iced coffee can be hit or miss with me because I think some places make it too watered down (I normally do iced espresso...not Americanos, JUST espresso), but the iced coffee here tasted strong & the vanilla flavoring was good (not the really artificial tasting vanilla at a lot of other coffee places).
I didn't look at a menu (or ask about a size), but I got what I'm guessing was a large. It was a little pricey, but not too bad (I think the novelty aspect factors into things here). They also do some sort of loyalty program. I didn't ask specifics, but I did get a text after giving my phone number.
I'll be back!
