My wife had the same as I, but without the tendon. She was understandably happy with it. The broth was beefy and flavorful--this restaurant has perhaps the best broth of all the pho broth we've tried in the Bay Area. The boys split a large chicken noodle soup. It too was a success, as Pho Thanh Long consistently has far and away the most tender pho chicken to be found in and around Santa Clara.
Despite the letdown in my dinner tonight, we'll certainly be coming back. The value and (up until tonight) the quality are both undeniable. The large bowl for almost all the pho options is only $6.75, and a large here is more substantial than a large at other pho restaurants. All that said, however, I'll be taking a break from tendon for a while.
