Just slightly hipster without being too hipster. I've been twice now and I think I can safely say 416 Snack Bar is a solid 3.5 star for me.
Please don't go here expecting to eat a full meal. The snack portions are very tiny. If you were starving you could likely eat 5-6 "snacks".
The snacks are, however, perfect when you just want a small taste of food to pair with your beer or wine. It sort of reminds me of Greek bar/taverna culture (Where you are usually served some kind of small portion of food with a drink, even if it's a dish of 5 olives or a slice of bread with olive oil).
The menu is small. Bottled beer starting from $6 all the way up to $10. Glasses of wine start at $8. Snack are $3-$6 but most cost $5. I feel like they are just *slightly* overpriced for what you get; they are really tiny. My latkes ($5) were literally the size of ritz crackers, and you only get 2. But yes, they are delicious!
Great vibe and seems to be really busy no matter when you go.
