What kind of things did they ask/tell you? Everything I've heard just makes them sound so basic and useless.
This was my experience at Wells Fargo late March 2010:
My personal banker (generally you need $100k in any combination of Wells Fargo products to get a personal banker, but they'll bend that in half that if you seem like a good customer) asked if I wouldn't mind talking to an investment banker. I said yes and a few minutes later was whisked away to a meeting room with the three of us. He asked about income, goals, investment styles, conservative vs aggressive, tax strategy, etc. He wanted to know the exact balances of every account (401k, savings, checkings, taxable investments, IRAs, etc) and how those were invested.
Then he described various types of investing that was available and his investment strategy. He made several suggestions (TIPS and gold) after seeing my goals which at the time were short-term stability while the stock market was on its way down. Then when the stock market was down he suggested some of Wells Fargo's mutual funds.
The problem for me was that Wells Fargo's funds were too limited in choice and had high overhead fees. I thought TIPS weren't going to cut it for me and at the time thought gold couldn't go any higher. I eventually kept it in money market accounts for 4 months, then plunged it all into stocks in Vanguard in July 2010. Waiting was good, and I got in at the lowest point in the last ~3 years. I'm up about 20% on that money in 1.5 years.
If I kept his advice, I'd be up nothing on the TIPS and I'd be up 60% on the gold. If I had gone in 50/50 with his advice I'd be up 30%. In the end he would have done a bit better than I did. But I doubt that I would have had the guts to stay in gold up to $1800/ounce and likely would have gotten far lower returns. That and I was up over 40% not too long ago on my own and will be again if the stock market returns.
As for US Bank, I was at a retirement reception for my father and their investment banker knew I was looking for investments. We chatted at the retirement reception and he invited me to talk, but I declined for now.
