Pascal's in Hove. Best place to eat in town.
That's the best call in Hove for a business lunch in Hove. Staff are discrete and can have a discussion. Havana Spoon is far too blingy and too full of local 'faces' that if you are doing proper business, you just look out of place a bit and feel other diners listening in a bit too closely. In Brighton, as much as I don't like chains, Hotel Du Vin is the number 1 for business in my experience. Unless into media/advertising industry, avoid places like the Seattle and Myhotel as nothing professional about either the locations or the staff...
