Translation:Have you been to this shop?
你来过这家商店吗 你 = you 来过 = Have been/come， 过 makes a verb perfect tense. ('Have' done something) 这家 = This. 家 is a measure word tor shops, companies etc. 商店 = Shop / store 吗= Question marker, ie yes or no.
So, it is literally- "You have come to this shop, yes or no ?" Or in better English Have you come/ been to this shop (before) ?
