For a satisfying lunch near the St. Pancras railway station, head to Shrimpy's, a new restaurant in a former gas station opened by the owner of the hip Shoreditch restaurant, Bistrotheque. The decor is vintage Californian and the food is artful Peruvian. Everything we had was delicious, but I especially enjoyed the tuna tostada topped with avocado and fried onions and the pineapple crisp, pictured, a ceviche-like tower with mascarpone cream and a "salsa" of chopped pineapple and raspberries.
