I visited Wilson's The Pub at The Lalit Great Eastern in Esplanade for a friend's bachelor brunch sometime back and was pleasantly surprised by an all-white glass house bar in the city. Tucked away in the Lalit - Great Eastern its perfect for a 50-60 people sun-downer. They had an open beer kiosk where you can grab a bottle uncork and take off, no need to wait for someone to serve.

More options in main course food would be great.
