This week I’m in London to meet with a client and some colleagues. I took the Virgin Atlantic overnight flight and was very impressed — in coach, we received a travel bag of nice amenities, a hot moist towelette in the morning, every flight attendant was super friendly, they even came around with a basket of candies…. it was overall a very pleasant experience. The flight was half empty so I had four seats to stretch out and sleep.  
The Heathrow express train was super easy — 20 mins to Paddington station and my hotel was a short walk away. 
That afternoon I explored London via the Underground (aka tube) to Brick Lane, a very artsy and eclectic area. Curry houses, vintage markets, tons of food stalls, street performers and a lot of street art.
I went to Kings Cross to find Platform 9 3/4, took the train to Piccadilly Circus, walked to Trafalgar Square to take part of the Irish festival in honor of St Patrick’s Day, made my way to where the changing of the guard takes place, swung by 10 Downing Street, and at Westminster Abbey I hopped back on the train towards Paddington. 
Grabbed an aged cheddar and caramelized sandwich at a pub located across the street from where Alexander Fleming invented penicillin before heading back to the hotel.
