You could be forgiven for not seeing much happening in this photo.   But looks can be deceiving…  Hiding behind this humble and signless façade, at 2821 Ocean Park Blvd. in Santa Monica, is the Westside’s newest and much-anticipated Vietnamese restaurant Blossom, that I first told you about back in April. You’ll be pleased to know that they are now open and dishing noodles Monday through Saturday for lunch and dinner.
