Always love SLF for their fuss-free and affordable hotpot sets (starting from $9.90). Don't care much for the toys but I know they're pretty popular too! Their tomyum and tomato soups are pretty legit, and their sets are also pretty filling for 1pax.
Their Harbourfront outlet seems to be running a promo where their freeflow drinks+condiments+ice cream is only an additional $1/pax. What a steal!
