I was glad to escape from the heat and the scrum of Chinatown into the India Emporium which is a pretty interesting shopping experience I itself. I recommend taking the elevator straight up to the forth floor if you're hungry and meandering back down via the escalators, taking in some of the stalls as you wander and browse. The fabric floor is particularly spectacular - rarely have I seen such a concentration of lace, sequins, and gold thread. I loved it!
Anyway, on to the food...there's also an Indian Vegetarian restaurant in the 4th floor food court but I headed straight for Kran Boom, inspired by the listing here. I expected to see preprepared food I could point to and stood around looking confused for a few seconds when I saw only a few fried snacks and ingredients for juicing. The 6 or so staff working kinda did too until I said, "sawasdee kaaa" and someone handed me an English menu. The range was great and dishes priced between 40 and 60 baht which is cheap for cooked to order vegetarian food, even in a food court. Since it was my last day in Thailand, I couldn't help myself so ordered too dishes - the wonton and cucumber salad and tofu with pepper.
When my food arrived I wondered whether I would regret my big order...but it turned out fine! The portions are generous for the price but not huge. The wonton salad consisted of fried wonton skins (no filling, to my surprise!) with super fresh crunchy cucumber, tomato, spring onion, finely sliced raw onion, plenty of herbs (mainly coriander), and a lip-puckeringly tart citrus dressing. The tofu was silky but firm and it's sauce was warm and spicy with green peppercorns as well as cracked black pepper giving it heat.
Staff are nice, food is prepared quickly, food court is clean (if that bothers you). All in all, I'd recommend this place for a quick bite as a respite from shopping and exploring in the heat if you're in the area.
