If you're into trying new types of foods and restaurants then CayDa should be on your list of places to go. Since there are only 2 Vietnamese restaurants in the Boca area, CayDa hits the spot when you're craving that spicy dish or flavorful noodles. This place is very small, maybe 12 tables at the most in the entire establishment, and it is a little bit on the pricey side (about $14 a plate on average) but the food is as authentic as it comes. The staff is very nice and always welcoming but the decor is a little lacking which seems to be typical for a Vietnamese restaurant. The only downfall is that they close at 8pm, so check it out early!
