Yes, Pi may be a trendy gathering place for certain groups of people, but for those who have dietary restrictions, it is not a first choice place. If one is looking for a low fat menu, he will have to accept salad as his only choice. For those who may enjoy the delights of cheese and creamy fare, then this is the place.
One curious practice is the extra charge for ordering an alcohol drink "neat." I was charged $1.00 for no ice. When I questioned the waiter, I learned I might also be charged for ice. If charged extra either way, why not add the cost to the beverage price? And why charge extra at all? To make the drinks look more pleasing. The quantity is not at all generous for the price.
