This place at 27 Tanjong Pagar Road (6327-8378) has a bit of a cult following - I believe for its truffles as well as its friendly owner. It's a bit hard to find as it's tucked away into the shophouses, and it also has an exclusive little private table sitting inside the wine cellar, no doubt adding a bit to the "cool" factor. The crowds were definitely in full force tonight - and on a Tuesday, no less.
Food-wise, the quality is very good. They brought us a surprise tomato-based starter before reaching the carpaccio with black truffles, which added a unique dose of muskiness to the plate. Interestingly, the minestrone was clear and thin rather than being tomato-based. It was refreshing, but beware that the soup comes in these huge bowls that may be better shared by two, lest it fill your stomach too quickly.
The breading on the vitello milanese veal was very light (and non-oily), and was probably one of the best that I've had. The fettucine alfredo was also very very rich, thus making it very addictive. Finally, we finished the meal with some simple gelato and sorbetti.
Despite how good it was (and the service was great too), I'd still choose Cantina over this place. The prices at Oso aren't cheap (especially if you order something with truffles - and we didn't even go for the more expensive white truffles), so I'd probably save Oso for a business meal. The food was of course good, but to really satiate the personal cravings, I'd rather hit up the linguini al granchio at Cantina.
