Myself and my husband will be visiting London from abroad this weekend. I am dying to go to J Crew, Cos, R&B and Uniqlo etc . My husband thinks we should shop near Euston Square as there are nice restaurants nearby. Is this a good plan or should I head to regent st first and meet him for lunch at euston square? Won't have a lot of time for shopping so want to make the most of it but also want to go where the best shops are! Thanks!
