Houston's restaurant in Memphis has been popular for all of the 25 years I've eaten there. I rated it excellent in the past, with an unbeatable chicken salad with peanut sauce and tortilla strips; prime rib sandwich; and the best couscous in the South. Things were consistently excellent. Changes over the decade have not been received well by us. The salad is changed, the prime rib sandwich is gone and the couscous is now insanely sweet. But the most recent change was reduce service to the tables on the patio, or so the receptionist told us. We sat there and had drinks and appetizers only while we observed nicer dressed people have full dinner served to them. Eventually we got a table indoors and the fish we had was good; but what was once a consistently excellent restaurant is changing, with every change for the worst.
