For five years, The Mighty Bowl has been a hero of the local food scene, doling out rice-and-bean bowls from a food truck and, later, a downtown walk-up window. But you might say it always had a kryptonite — seating.Well, not anymore. On Tuesday, The Mighty Bowl got mightier when it officially opened a 3,000-square-foot restaurant at 108 W. Eighth St. in Vancouver. Crowds there found an expanded menu and seats at tables, bar stools and even on bleachers.The new location is open 8 a.m. to 3 p.m. Monday through Friday and seats 44. Owner Steve Valenta said there are plans to add dinner and weekend hours by winter, contingent on the hiring of 10 more staff.The day before the opening, Valenta seemed relieved during an interview. It took nine months to retrofit the space, formerly a Chinese food restaurant, with construction taking place in addition to normal business hours.“Sixteen-hour days get old,” he said, laughing.Customers seemed happy for the hard work. A line formed out the door around the lunch hour.Three more bowls, four salads and a smoothie and juice bar mark new additions to The Mighty Bowl’s menu. Breakfast offerings include items like avocado toast and acai bowls. That’s a lot of new compared with its previous menu of one, the eponymous mighty bowl.
