I don't recommend Serendipity 3 at all. Waited about 20 min for a table; then another 10 min in line for the bar to-go order, I was next in line when B. got a table while waiting outside.
Ordered a regular Frozen Hot Chocolate which is way overpriced at $10 for a small. I wanted No whipped cream - still got it so had to scrap it off. It doesn't taste any better than a McDonald's milkshake.
Don't waste your time & money here.
