Spring is in the air. Baseball spring training is underway,  people are starting to get Covid vaccines, and restaurants are either re-opening with some indoor seating, or opening for the first time.  One of those places is El Muchacho Alegre, 111 Airport Way, Renton. The location, built as a burger joint in the 1950's, has gone through many incarnations. It was most recently a hookah bar, before that a Bangladeshi restaurant, before that Vietnamese, and had a long run as Lermond's, a diner-like place. El Muchacho Alegre opened a couple of weeks ago.  I often like to wait a couple of weeks before trying a new restaurant, to give them a chance to work out the kinks. But this time, we went on their second night of business. I like seafood, and I like Mexican food, and the place is close by.  Anyway, the place is good, and they had their act together even on the second night of business. They make a green salsa that is served with warm chips, that is both flavorful and quite hot.
