Wow, some of the best Thai food I've had. We started with fresh shrimp spring rolls which came with a sweet teriyaki peanut sauce. The appetizer was good, but the main entrees was outstanding!
I had the red curry with shrimp at a spicy level of 10. This was an actual 10. The kitchen uses fresh red chilies which make for a very spicy dish. I needed four napkins to blow my nose and wipe my tears. This might not be ideal for all; however, for those seeking serious spiciness, then smiling banana leaf has what you're looking for. Overall, it was an excellent curry. If you're not a fan of overly spicy dishes, then you can have the dish prepared at a lower spice level.
One of the drawbacks is that the restaurant is quite small. We had to wait 30+ minutes for a table for two without a reservation. This wasn't a terrible inconvenience since there is a pub down the street. Just note that SBL is quite busy on Saturdays between dine in patrons and take out orders.
I would rate this restaurant four and a half stars if I could.
