When we got a tip that King of Thai Noodle House was offering cheap food and drinks and the complete sports lineup on big-screen TVs, we had to admit skepticism. King of Thai Noodle House?

We joined a good-sized crowd for the NCAA final on Monday, where we sipped $2 drafts (Sierra Nevada, Fat Tire, Amstel Light, Sapporo), then switched to tasty and gigantic $6 margaritas, prepared by an efficient and friendly trio of Thai women.
