$4.00 for 500 ml of bottled water. Expensive!!! You can get a beer for $4 in the hotel resturant. The beer may not be as good for you but $4 for water from the tap at Aquafina plant in Houston?!
The Tokyo One is next door to the Holiday in Houston on the Beltway and Westheimer. This place is the best place for eating all you can eat sushi. Very good variety.
