The 5pm Dining blog was invited along to see what's cooking.
Apparently, brunch was invented by an Englishman who was keen to soothe away his Sunday hangovers.
With the launch of their new weekend brunch menu, Galvin Brasserie de Luxe is a chic locale for a spot of brunch irrespective of how delicate you may or may not be feeling.
It is a concise menu split into small plates, large plates plus a cocktails and specialities section which details all the teas, coffees, smoothies and alcoholic drinks on offer.
If you want to kick start your brunch with a spicy blast then their Bloody Mary will do the job. Alternatively, their smoothies are satisfyingly thick and creamy.
The small plates section comprises five, lighter options. Typical choices include the croissant with berries and granola; a charcuterie and cheese board or the roast Portobello mushroom with rocket and pesto on rye bread.
The small plates section also includes that evergreen favourite, eggs Benedict.
Chunky steak sandwich
We ate from the big plates selection. Passing over the full Scottish breakfast and the poached egg, avocado and tomato salsa on rye, we ordered the flat iron steak sandwich and a dish of baked duck egg, truffle, potato and Parmesan.
The steak sandwich is a chunky affair with about eight thick slices of beef cooked pink. It comes on a crisp baguette with a slather of caramelised onions and peppery rocket.
If you are feeling very peckish then this is a healthy portion which will set you up for the day.
On the other side of the table, the duck egg dish came on a hot skillet. Gooey and rich with truffle, this is an ideal comfort food; the sort of dish that would keep you warm on a cold afternoon at Murrayfield.
As you would expect in a five star hotel, the service is crisp, polished and friendly. With its gleaming white tiles, high windows and eye-catching island crustacean bar, the Brasserie's interior is as smart as the service.
The Brasserie's brunch menu is available from noon to 2.30pm on Saturdays and Sundays.
If brunch is not your thing then both the Galvin Brasserie de Luxe and The Pompadour restaurant on the first floor have several other menus to choose from.
5pm currently has Big Deals for both restaurants. This Deal with the Brasserie is £39 for two people to each have three courses from the seasonal menu, a glass of house wine and tea or coffee.
Alternatively, this Big Deal at The Pompadour by Galvin is for two people to have the five course Discovery menu with paired wines plus tea or coffee.
