I've tried the weekday buffet, and it's great, not too spicy, good variety of selections. Sunday's menu, adding Indian street food (bhel puri, I hope!), sounds great. From the Tampa Bay Times review:
"... At lunchtime, there is a buffet, $10.99 Monday to Saturday, $12.99 on Sunday when the kitchen steps it up a little, offering interesting Indian street foods and some southern Indian specialties. The other six days, you'll usually find five vegetarian curries (one spinach, one mild korma; usually two mild and two a little spicier), one goat dish, chicken tikka masala, tandoori chicken, some kind of biryani or vegetarian pulao, and a couple of desserts, one hot and one cold. There are pakoras and chutneys and pappadam and naan, all the accoutrements to enliven an already fairly exciting meal..."
Please be prepared to pay for the buffet in cash since it will be the same price for everyone and will make it easier for the hosts and restaurant. Ask for Elizabeth's table.
