The tour is worth doing as it does point out a number of places to see in Seoul. However it was a bit rushed and I could have used more time in some spots and less in others. The guide was good at improvising as one of the attractions was closed due to rain so I got to see another spot nearby.
The tour guide wasn't very informative and his English could have been better, luckily he had 2 trainees with him who could communicate well and were much more knowledgeable.The tour description didn't match the real thing as I was taken to a museum and spent an hour in there instead of "ambling down the streets seeing numerous markets, temples and tea houses"(didn't see one tea house and certainly didn't try any Korean food on this tour). The places I was taken you can easily see on your own. I was expecting lanes and alleys, places I perhaps wouldn't venture down for fear of getting lost.
